a girl starts from a point A and walks 285meter to B on a bearing of 078°.She then walks due south to a point C which is 307meter from A. What is the bearing of A from C, and what is |BC|?

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

Write the standard form of an equation with (see picture below)

Cd is the perpendicular bisector of both xy and st, and cy=20. find xy.
